In dancing, there are modern dancers (i.e. Ruth St. Denis, Mary Wigman, and Martha Graham) and those who perform the more classical ballet (i.e. Mikhail Baryshnikov, Gelsey Kirkland, and Rudolf Nureyev). In writing, we have New York Times best sellers, and classical literature like George Eliot, F. Scott Fitzgerald, and Henry James. In music, we have the rock and country genres (for example), and we have classical music. In dog training, we have the modern methods and modern tools, and we have the old fashioned teaching of mechanics and no tools but a leash and a collar.
